No Pins for H and L
the product didn't come with a jumper set and there were no pins for the H and L although they were in the photo!

Good working
working good with arduino.

Works good!
I ordered for my kid for experimenting with Arduino, he says they work great

Works as expected
Function: My order included 3 units. Each of these worked. The device has controls for adjusting duration triggered and sensitivity (detection distance). Once triggered the duration ranged 1sec to 6min. These values are consistent w/ the datasheet. I did not test sensitivity. Electrical Characteristics: Sensor pin output (Vout) range 3.19-3.33v across the input range tested (4-7v, datasheet recommended VCC range: 5-20v). PCB is approx. 24mm by 32mm (15/16inch x 1 1/4inch). Solder joints are clean. Would buy again.

Who goes there?
Nifty little motion sensor. Easy to code and use with Arduino or Pico 2W. Nice feature is the ability to adjust time delay and sensitivity.

Hard to get the hang of it
Good sensitivity is excellent and the delay dosen't stand for time taken to give signal it means the time of signal on
